Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a frontier of fundamental physics. Yet in laboratories around the world, carefully ...

A quiet revolution is taking shape in the world of physics, and it doesn’t rely on exotic particles or massive particle colliders. Instead, it begins with something much more familiar—sound.

A stellar concert is playing out in the night sky, and scientists are learning how to listen to it like never before. Deep inside stars, sound waves move through hot gas, creating vibrations. These ...

Figure 1: Workflow for generating and reconstructing arbitrary acoustic images. In summary, we have introduced the acoustic hologram. Its 3D-printed surface profile encodes the phase of the desired ...

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...

These sound waves were then picked up by a receiver as a binary pattern with 1 being reflected sound waves and 0 being unreflected sound waves. This binary signal allows the UBL system to carry ...

Traditional computer chips run on electricity, while the emerging photonic chips use light. Now, scientists at Harvard have demonstrated a new kind of chip that transmits data in the form of sound ...
